The device features a 12.5-inch HD screen, supported by an Intel processor, 4GB of RAM and 128GB of storage.

Pairing the 7mm-thick keyboard with the tablet provides the laptop element of the Transformer Book V with both operating systems - the keyboard is also battery-less and can house up to 1TB of additional storage space.

An Android 4.4 smartphone slots into the back of the screen to become the Android part of the laptop/tablet viewable on either Windows 8.1 or the main Android OS.

When removed, the smartphone acts like any other for call-making and accessing handheld Android apps. It features its own 5-inch screen with a powerful 64-bit Intel Atom Moorefield processor and LTE.

There is also 64GB of storage on board the smartphone - which weighs 140g and is 11mm thick - as well as 2GB of RAM, a 2,500mAh battery for about 10 hours of usage, an 8-megapixel camera on the back and a 2-megapixel snapper on the front.

Asus is yet to reveal the exact pricing and release date of Transformer Book V.
